Field Summary

Fields

Modifier and Type	Field and Description
protected java.util.Hashtable<java.awt.Component,RowFlowLayoutConstraints>	comptable This hashtable maintains the association between a component and its rowflow constraints.
protected RowFlowLayoutConstraints	defaultConstraints This field holds a rowflow constraints instance containing the default values, so if a component does not have rowflow constraints associated with it, then the component will be assigned a copy of the RowFlowLayoutConstraints.
protected RowFlowLayoutInfo	layoutInfo
protected static int	MINSIZE The smallest size that can be laid out by the rowflow layout.
protected static int	NORMALSIZE The normal size that can be laid out by the rowflow layout.

Field Detail

MINSIZE

protected static final int MINSIZE

The smallest size that can be laid out by the rowflow layout.

Constant Field Values

NORMALSIZE

protected static final int NORMALSIZE

The normal size that can be laid out by the rowflow layout.

See Also:

Constant Field Values

defaultConstraints

protected RowFlowLayoutConstraints defaultConstraints

This field holds a rowflow constraints instance containing the default values, so if a component does not have rowflow constraints associated with it, then the component will be assigned a copy of the RowFlowLayoutConstraints.

See Also:

getConstraints(Component), setConstraints(Component, RowFlowLayoutConstraints), lookupConstraints(Component)

comptable

protected java.util.Hashtable<java.awt.Component,RowFlowLayoutConstraints> comptable

This hashtable maintains the association between a component and its rowflow constraints. The Keys in comptable are the components and the values are the instances of RowFlowLayoutConstraints.

See Also:

util.RowFlowLayoutConstraints

layoutInfo

protected RowFlowLayoutInfo layoutInfo

Constructor Detail

RowFlowLayout

public RowFlowLayout()

Creates a Row-FlowLayout layout manager.

Method Detail

setConstraints

public void setConstraints(java.awt.Component comp,
                           RowFlowLayoutConstraints constraints)

Sets the constraints for the specified component in this layout.

Parameters:

comp - the component to be modified

constraints - the constraints to be applied

getConstraints

public RowFlowLayoutConstraints getConstraints(java.awt.Component comp)

Gets the constraints for the specified component. A copy of the actual RowFlowLayoutConstraints object is returned.

Parameters:

comp - the component to be queried

Returns:

the constraint for the specified component in this rowflow layout; a copy of the actual constraint object is returned

lookupConstraints

protected RowFlowLayoutConstraints lookupConstraints(java.awt.Component comp)

Retrieves the constraints for the specified component. The return value is not a copy, but is the actual RowFlowLayoutConstraints object used by the layout mechanism.

If comp is not in the RowFlowLayout, a set of default RowFlowLayoutConstraints are returned. A comp value of null is invalid and returns null.

Parameters:

comp - the component to be queried

Returns:

the contraints for the specified component
